John Steinbeck’s novella Of Mice and Men explores themes of morality and masculinity through its many male characters. With the use of hegemonic masculinity theory, this essay analyzes how different elements of masculinity are characterized, constructed, and valued in relation to one another. Masculinity is defined by a utilitarian sense of purpose, systematic loss, and homosocial desire in Of Mice and Men. The men in this novella yearn for connection and meaning, in contrast to the inevitable nature of violence presented in the novella. Ending the life of an animal or a man that has lost its purpose is considered a compassionate and unavoidable act. In this way, hegemonic masculinity in John Steinbeck’s Of Mice in Men is defined by a duality of homosocial desire and utilitarian violence.
